Abstract

A medical apparatus includes a trocar assembly including a cannula and a trocar. The medical apparatus also includes a sleeve having a number of sealing members extending therefrom, and a passageway extending therethrough, with the trocar assembly being positioned within the passageway of the sleeve. The medical apparatus further includes a sealing member which defines a flexible, gas impervious bag having an interior void and a charge of beads confined within the interior void. The medical apparatus still further includes a lock member, and a sealing member having a biologically active compound disposed thereon. The sleeve is positionable within an opening defined in a wall of a body cavity. Moreover, the sealing members are movable between (1) a first orientation in which the sealing members are positioned to facilitate advancement of the sleeve into the opening, and (2) a second orientation in which the sealing members are positioned to prevent fluid communication between an area inside of the body cavity and an area outside of the body cavity through a space defined between the opening of the body cavity and the sleeve. A medical procedure which uses the medical apparatus is also disclosed.
